SQL Pivot with Union All - sql

Question

I'm using SQL Server 2012. I have 2 pivots (Current Year (CY) vs Last Year (LY) that work fine by themselves but want to Union them and have the results all togeather, how do I go about this? I need to have the data look like like this:
Cost Centre Name May_CY May_LY Jun_CY Jun LY.....This_Yr_Total Last_Yr_Total
This is my code:
SELECT
pvt.*,
Isnull(pvt.jan_CY, 0) +
Isnull(pvt.feb_CY, 0) +
Isnull(pvt.mar_CY, 0) +
Isnull(pvt.apr_CY, 0) +
Isnull(pvt.may_CY, 0) +
Isnull(pvt.jun_CY, 0) +
Isnull(pvt.jul_CY, 0) +
Isnull(pvt.aug_CY, 0) +
Isnull(pvt.sept_CY, 0) +
Isnull(pvt.oct_CY, 0) +
Isnull(pvt.nov_CY, 0) +
Isnull(pvt.Dec_CY, 0)
AS This_Year
FROM (SELECT [CostCentre], [CostCentreDesc] AS Name, { fn CONCAT(DATENAME(month, dbo.tblGLS215_2016_2017.AccDate), '_CY') } AS AccMonth, [RecordedAmount]
FROM [tblGLS215_2016_2017]
WHERE Employee <> '') AS s PIVOT (SUM([RecordedAmount]) FOR [AccMonth] IN (May_CY, Jun_CY, Jul_CY, Aug_CY, Sept_CY, Oct_CY, Nov_CY, Dec_CY, Jan_CY, Feb_CY, Mar_CY, Apr_CY)) AS pvt
UNION ALL
SELECT
pvt.*,
Isnull(pvt.jan_LY, 0) +
Isnull(pvt.feb_LY, 0) +
Isnull(pvt.mar_LY, 0) +
Isnull(pvt.apr_LY, 0) +
Isnull(pvt.may_LY, 0) +
Isnull(pvt.jun_LY, 0) +
Isnull(pvt.jul_LY, 0) +
Isnull(pvt.aug_LY, 0) +
Isnull(pvt.sept_LY, 0) +
Isnull(pvt.oct_LY, 0) +
Isnull(pvt.nov_LY, 0) +
Isnull(pvt.Dec_LY, 0)
AS Last_Year
FROM (SELECT [CostCentre], [CostCentreDesc] AS Name, { fn CONCAT(DATENAME(month, dbo.tblGLS215_2015_2016.AccDate), '_LY') } AS AccMonth, [RecordedAmount]
FROM [tblGLS215_2015_2016]
WHERE Employee <> '') AS s PIVOT (SUM([RecordedAmount]) FOR [AccMonth] IN (May_LY, Jun_LY, Jul_LY, Aug_LY, Sept_LY, Oct_LY, Nov_LY, Dec_LY, Jan_LY, Feb_LY, Mar_LY, Apr_LY)) AS pvt
Any help would be greatly appreciated.
This is one of the pivots for 'This Year' that returns results:
SELECT
pvt.*,
Isnull(
pvt.jan,0)+ Isnull(pvt.feb,0)+ Isnull(pvt.mar,0)+ Isnull(pvt.apr,0)+ Isnull(pvt.may,0)+ Isnull(pvt.jun,0)+ Isnull(pvt.jul,0)+
Isnull(pvt.aug,0)+ Isnull(pvt.sept,0)+ Isnull(pvt.oct,0)+ Isnull(pvt.nov,0) AS This_Year_Total
FROM
(
SELECT
[CostCentre],
[CostCentreDesc] AS Name,
CONVERT(
CHAR(4),
AccDate,
100
) AS [Month],
[RecordedAmount]
FROM
[tblGLS215_2016_2017]
) AS s PIVOT(
SUM( [RecordedAmount] ) FOR [Month] IN(
May,
Jun,
Jul,
Aug,
Sept,
Oct,
Nov,
DEC, Jan, Feb, Mar, Apr)) AS pvt
